Wild-type Sp77.15 ± 2.1 A0.1 ± 0.01 A0.07 ± 0.018 A0.058 ± 0.008 A
phbC mutant19.3 ± 4.2 B0.19 ± 0.04 B0.19 ± 0.03 B0.17 ± 0.03 B
  • a The values are means ± standard errors for three replicates from one representative experiment. Each experiment was carried out three to five times, and similar results were obtained each time. Within a column different letters after values indicate that there is a significant difference at a P value of 0.05, as determined by a t test.
